Synthesis of N,N′-Di-(phenyl-3,5-dicarboxylic acid)-perylene-3,4,9,10-tetracarboxylic acid diimide ligand (1): PTCDI-Tetracraboxylic acid
[0095]A mixture of 0.500 g (1.274 mmol) of 3,4,9,10-perylene tetracarboxylic dianhydride, 0.694 g (3.823 mmol) of 5-amino isophthalic acid, 20 g of imidazole and 0.100 g (0.456 mmol) of zinc acetate was heated at 150° C. for 20 h under argon atmosphere. Mixture was cooled and 100 ml of 2N hydrochloric acid was added for precipitation of product. The precipitate was collected by vacuum filtration and washed with a mixture of methanol and water. The product 1 was dried at 100° C. for 12 h.
[0096]1H NMR of PTCDI (400 MHz; D2O, 25° C.). δ (ppm)=8.43 (s, 2H), 8.35 (s, 4H), 8.02 (m, 8H)
[0097]IR (KBr) ν max=743, 808, 851, 1118, 1251, 1353, 1573, 1596, 1664, 1698, 2974, 3154, 3410 cm-1.

Complexation of Ligand with Zn(II) Ion (2)
[0098]Zinc nitrate hexahydrate (0.087 g, 0.291 mmol) and 1 (0.060 g, 0.081 mmol) were dissolved in DMF / 1,4-Dioxane / H2O Ratio 3:1:1 in Teflon liner. The reaction mixture was heated in oven at 100° C. for 3 Days. The reaction vessel was then removed from the oven and allowed to cool to room temperature. Product was washed with DMF, methanol and chloroform.
[0099]IR (KBr) ν max=751, 806, 853, 1119, 1243, 1346, 1589, 1660, 1697, 2984 cm-1.
example 3
Microcrystalline Metal Coordinated Assembled Material (2)
[0100]A mixture of 0.500 g (1.274 mmol) of 3,4,9,10-perylene tetracarboxylic dianhydride, 0.694 g (3.823 mmol) of 5-amino isophthalic acid, 20 g of imidazole and 0.100 g (0.456 mmol) of zinc acetate was heated at 150° C. for 20 h under argon atmosphere. Mixture was cooled and 100 ml of 2N hydrochloric acid was added for precipitation of product. The precipitate was collected by vacuum filtration and washed with a mixture of methanol and water. The product PTCDI-TC 1 was dried at 100° C. for 12 h, The product 1 was then reacted with zinc nitrate to form the metal coordinated assembled structure 2, wherein zinc nitrate hexahydrate (0.087 g, 0.291 mmol) and PTCDI-TC (1) (0.060 g, 0.081 mmol) were dissolved in DMF / 1,4-Dioxane / H2O Ratio 2:1:1 in Teflon liner. The reaction mixture was heated in an oven at 100° C. for 3 Days. The reaction vessel was then removed from the oven and allowed to cool to room temperature. Microcrystalline ...
